support C++11 that we now require.

Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`.  Use `clang-format` version 6.0.

UBsan causes our test crash to abort instead.  Switch the test to
explicitly abort when sanitizers are in use.

Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace KWSys per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online
information available from "https://cmake.org/licensing#kwsys".

Run the `filter-notices.bash` script to perform the replacements mechanically.
Manually fix up the shebang line in one file.

The clang-format tool sorts `#include` lines within contiguous blocks.
Separate blocks with blank lines and sort the include lines within them
so that clang-format does not re-order anything.

Teach testProcess-1 to stress-test kwsysProcess for leaks that lead to
failure by running the test many times.

Store and pass the interruptDelay parameter as 'unsigned int' so
it does not have to be converted to pass to testProcess_sleep.
Otherwise some compilers warn about the signed->unsigned conversion.

Two new tests were added to testProcess:
 * Test 9 is constructed of the root test process, a child process,
   and a grandchild process.  The grandchild ignores all Ctrl+C signals
   and then sleeps.  The child runs the grandchild normally.  The root
   process runs the child in a new process group, sends it a Ctrl+C
   signal, and then lets the process expire to prove that the child was
   blocked waiting for the uninterruptable grandchild to die.
 * Test 10 is constructed of the root test process, a child process,
   and a grandchild process.  The grandchild sleeps and processes
   signals normally.  The child runs the grandchild in a new process
   group.  The root process runs the child in a new process group as
   well, sends it a Ctrl+C, and then verifies that: (1) the child does
   indeed terminate with an interrupt signal, (2) the child did not
   expire, proving that it retransmitted the signal to the sleeping
   grandchild before waiting for the grandchild to terminate.

assert() calls to tell Clang scan-build that we do not expect certain
pointers to be NULL.

Some compilers, notably Clang, will warn at compile time (or
runtime with debug flags) if they detect a null dereference.
Try to outsmart them by dereferencing an address a little
larger than NULL.

Clang is smart enough to recognize that "*(int*)0=0" invokes undefined
behavior, warns, and produces an "undefined instruction".  The message
in commit "Avoid Clang optimizer bug in testProcess-[45]" (2010-07-02)
is incorrect; this is not a Clang bug.  It really is undefined
behavior.  Use "*(int*)1=0" to produce a crash instead.

Clang's optimizer, as of clang version 2.8 (trunk 107463), produces the
undefined instruction 'ud2' for the code "*(int*)0=0" on OS X x86_64.
It causes our crash tests to fail because the child process exits with
an invalid instruction instead of a segmentation fault.  Work around the
bug by using "*(int*)1=0" in this case.

Fix warnings in CMake source code. Suppress warnings in Lexer and Parser files that are 'too hard' to fix.

This converts the KWSys license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the KWSys copyright to
cover the full development time range.

The test is supposed to terminate quickly when its child crashes, but
that seems to take over 10s on busy systems.  This extends the test's
timeout to 30s to help it pass when running on a busy system.

ENH: Changes based on patch from Ryan C. Gordon to enable process execution on BeOS.  There seems to be no way to implement it without polling (or threads).

ENH: Extended test 0 to run the executable twice using the same process object.  This tests the reusability of the objects.

BUG: Use sleep(1) instead of usleep(1000000) because some UNIX systems specify that the argument to usleep must be less than 1000000.
